>
> The code path in ObjectStore.java currently leaks BoneCP (or Hikari)
> connection pools when a new configuration object is passed in. The code needs
> to ensure that the persistence-factory is closed before it is nullified.
> The relevant code is
> [here|https://github.com/apache/hive/blob/master/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L290].
> Note that pmf is set to null, but the underlying connection pool is not
> closed.
